manage the household without having the kids pitch in?
We couldn't do it. My sons are 5 and 7, and they contribute a lot. Their help is invaluable.
They are responsible for watering plants, managing all of their backpack and lunchbox packing and unpacking, keeping their toys and laundry picked up and put in the right places, cooking tasks (like peeling garlic, tearing lettuce for salads, washing vegetables, picking basil or cilantro), getting the mail, cleaning the bathroom mirrors, handling all self-care stuff, emptying the dishwasher, helping to set and clear the table etc etc. They really do a lot, and it helps!
How do busy families even live, if everyone isn't pulling their weight to the best of their ability?
